A new pigment, phlegmacin A 8,8’-di-O-methyl ether (1), was isolated from fruiting bodies of Xy- laria euglossa (Ascomycota) along with the known fungal pigments (S)-torosachrysone-8-O-methyl ether (2) and emodin-6,8-di-O-methyl ether (3). The structure of compound 1 was established on the basis of its spectroscopic data and the absolute configuration determined as P and 3’S by comparing the CD and1H NMR spectra of 1 with those of the phlegmacins 4 and 5. Compound 1 represents the first phlegmacin type pigment isolated from the ascomycete.

Key words: Xylaria euglossa, Ascomycota, Dihydroanthracenone, Phlegmacin A 8,8’-Di-O-methyl ether
